Description

The belted spiny eel is an eel-shaped spiny eel (Mastacembelidae) from fresh water of Southeast Asia, including the Mekong and Chao Phraya basins. The species grows to about 29 cm and has a strongly elongate, light-brown body with dark ring bars, a row of separate spinelets before the dorsal fin and a pointed, mobile snout. As a nocturnal bottom-dweller it buries itself in soft sand by day and searches at night for insect larvae, worms and small crustaceans. The fish is harmless to humans.
